WILLIAM E. RIVERS, OF OLD BRIDGE, NEW JERSEY.

SAGGAR.

To all whom it may concern:

Be it known that I, WILLIAM E. Rivers, a subject of the King of GreatBritain, and a resident of Old Bridge, in the county of Middlesex, inthe State of New Jersey, United States of America, have invented certainnew and useful Improvements in Saggars, of which the following is, takenin connection with the accompanying drawing and reference-numeralsmarked thereon, a complete, concise, and accurate description orspecification.

My invention comprehends certain improvements in saggars, such as areemployed for holding tile, brick, and analogous articles, formed of clayor other material during the process of firing; and the object of myinvention, is to provide a saggar of improved and simplifiedconstruction and of increased strength and durability over saggarscommonly in use of which I have knowledge.

Referring to the accompanying sheet of drawing, in which I haveillustrated an embodiment of my invention, I will proceed to describe indetail the construction and manner in which my improved saggar is made,and in which Figure 1 is a perspective view thereof showing thesupporting pins or rods in position to receive the tiles or otherarticles. Fig. 2 is a like view of one of the notched spacing orsupporting strips.

The saggar l which may be molded, stamped or pressed out is providedwith a plurality of vertical grooves -2 which preferably extend from thetop of the saggar to a point near the bottom thereof. These grooves areformed when and during the same operation that the saggar is beingmolded and formed.

3 indicates a plurality of supporting pins or rods upon which the tile,brick or analogous articles are placed preparatory to the firingoperation. These supporting pins or rods are of suiiicient length toextend from side to side of the saggar and their ends are held fromlateral displacement by being inserted in the grooves 2-.

4 indicates separating and supporting strips which are provided withside notches or depressions 5 in which the ends of the pins or rods 3are supported and be tween which they are locked. These separatingstrips may be of any length or width desired to meet the requirements ofthe Specification of Letters Patent.

varying thicknesses of articles to be supported thereby andtherebetween.

A saggar of my improved form does not require additional cutting orother manipulation subsequent to its leaving the mold to fit it toaccommodate the shelves or supporting members; thus lengthening andextending the life or service of the saggar beyond the life of thosewhich require either perforating, cutting or notching in order to formsuitable supports for the shelves or supporting rods, the latter havinga tendency to weaken the structure.

It will be apparent from the above description that I have produced asaggar of a very flexible character so far as one is enabled to adjustthe height of or distance between the tile supporting members toaccommodate the tile or other articles of vari ous heights. It will alsobe noted that the notches in the strips lock the pins or rods firmly inthe grooves and prevent them from moving or rocking during handling, orthe movement of the saggar to and from the kiln.

Another advantage of my invention is that the grooves may be, andpreferably are made, as has been pointed out, in the process of formingthe saggar itself, thus simplifying the method of manufacturing, andreducing the cost.

Having thus described my invention, what I claim as new herein anddesire to secure by Letters Patent is:

l. The combination of a saggar having walls provided with verticalparallel grooves, the upper ends of which are opened at the top, withmeans for supporting articles to be fired, said means consisting ofsupporting members extending across the interior of the saggar, anddetachably engaged in said grooves, and supporting and separatingstrips, provided with notches, in which the ends of said supportingmembers rest.

2. The combination of a saggar provided with grooved walls, with meansfor supporting articles to be fired, said means comprising supportingand separating members extending across the interior thereof, and havingtheir ends terminate in said grooves, and strips supporting andseparating the said supporting members.

3. In a saggar, the combination of supporting members extending acrossthe illterior thereof; means for supporting and locking the ends of saidsupporting members from displacement, said means comprising notchedseparating strips, in the notches of which the ends of the supportingmembers are supported.

4:. In a saggar, the combination of a plurality of supporting rodsextending across the interior thereof; retaining means in said saggarfor preventing lateral displacement of said rods, and means forseparating and supporting the rods, said means comprising notched stripsengaging and supporting their ends.

5. A saggar provided with a plurality of oppositely disposed grooves inits walls extending to the top; supporting members eX- tending acrossthe saggar andengaging said grooves; and supporting and separatingmembers interposed between the first named supporting members.

saggar provided with grooves open at the top; removable supportingmembers for supporting articles to be fired, said members engaging thegrooves and extending across the saggar; and members interposed betweenand supporting said removable supporting members.
